The Office of Inspector General is an independent office within EPA that performs audits, evaluations, and investigations of the Agency and its contractors, to promote economy and efficiency, as well as prevent and detect fraud, waste, and abuse.

We have ten Regional offices, each of which is responsible for the execution of our programs within several states and territories. To get information about activities in your Regional office, select the appropriate link.

Office of Research and Development Laboratories
These labs develop knowledge, assessments, and scientific tools that form the underpinnings of the vast majority of EPA's protective standards and guidance.

Office of Research and Development Research Programs
Six national research programs engage with outside partners and EPA programs and offices to identify the research priorities that are important for achieving EPA’s strategic goals and objectives.

Program Office Laboratories
These labs directly support regulatory implementation, compliance, and enforcement at a national level. For example, the National Vehicle and Fuel Emissions Laboratory performs motor vehicle standards testing.
